I'm looking to iterate through a JSON object in javascript. Right now it is loading each "item" into a single cell instead of putting 1 item per column across a row. For example, I want to get:
Period Name Amount
1/1/2014 Accounting $500.00
What I'm getting is:
Period Name Amount
1/1/2014, Accounting, $500 1/1/2014, Finance, $750 ...,...,...
The view producing the JSON object is:
def BudgetJson(request):
from django.http import JsonResponse
resultset = models.Expense.objects.filter(category_id=1)
d = {'data' : [[[model.expensePeriod, model.expenseName,
model.expenseAmount] for model in resultset]]}
return JsonResponse(d)
I'm using the datatables
library to render the table, and using AJAX to receive the JSON object (via a URL):
<script type="text/javascript" class="init">
$(document).ready(function() {
$('#expenses').DataTable( {
"ajax": '{% url "property:budget:budget_json" %}'
});
});
</script>
I understand that my view is outputting a single key/item, which is why I'm getting that result - what I want to know is, is it better to let the JavaScript loop through the JSON object, and is that possible using the datatables
UI library? Or should I change the structure of the JSON object that the view is outputting?
You can do this way,
producing JSON
Object:
def BudgetJson(request):
from django.http import JsonResponse
out_list = []
resultset = models.Expense.objects.filter(category_id=1)
for model in resultset:
temp_dict = {'expense_period': model.expensePeriod, 'expense_name':model.expenseName, 'expense_amount':model.expenseAmount }
out_list.append(temp_dict)
data = {'data' : out_list }
return HttpResponse(json.dumps(data), content_type='application/json')
and inside your <script>
tag the datatable
will as
$('#expenses').DataTable( {
"ajax" : "your-url",
"columns" : [
{"data" : "expense_period"},
{"data" : "expense_name"},
{"data" : "expense_amount"},
]
});
This will work. :)
